The character known as "Strega del nord" (Good Witch of the North) appears in the series' adaptation of *The Wizard of Oz*. As the benevolent ruler of Munchkin Country, she greets Dorothy immediately after the girl's arrival in Oz, which coincides with Dorothy's house crushing the Wicked Witch of the East.

She bestows upon Dorothy the silver shoes (or ruby slippers in certain versions) inherited from the defeated witch, detailing their protective magic and significance. Acknowledging Dorothy's longing to return to Kansas, she directs the girl to seek the Wizard of Oz in the Emerald City, instructing her to follow the Yellow Brick Road.

This counsel propels Dorothy’s journey, initiating her encounters with the Scarecrow, Tin Man, and Cowardly Lion. The witch embodies wisdom and kindness, providing crucial stability and direction in Dorothy’s unfamiliar surroundings. Her authority is recognized by the Munchkins, and she identifies herself as one of Oz’s two good witches, contrasting with the two wicked witches.

Her domain is the northern Gillikin Country, though the adaptation does not elaborate on this regional name. She appears elderly yet gentle, fitting traditional portrayals of a benevolent sorceress. Beyond this initial meeting, she takes no further part in Dorothy’s adventures. Her narrative role centers solely on catalyzing Dorothy’s quest through guidance and the gift of enchanted footwear.
